2.3 Principle of Element Management
The interface configuration for Element Management or Network Management systems is shown
in the next two figures for the ES10La/ES10XLa with embedded NEC (network element controller
= SNMP Proxy Agent) and the ES10L/ES10XLb.
Fig. 2.3.1: EMS/NMS Interface (a) ES10La/ES10XLa (b) ES10Lb/ES10XLb
The ES10La/ES10XLa versions (ref. to Fig. 2.3.1 a) contain an embedded network element
controller (NEC) which works as a SNMP Proxy Agent. All equipment (EDFAs, optical switches,
receivers and power supplies) which is connected to the RS485 master interface and which
support the BKtel RS485 protocol are polled. The received data is then translated into SNMP and
HTTP and can be accessed via the Ethernet interface or locally via the USB interface. The NEC is
able to poll up to 48 devices on the RS485 bus. On the I/O ports #1 … 5 warnings/alarms
collected from all polled devices can be accessed. The application software of the NEC can be
updated easily in order to support new devices. An overview of software releases is given in
chapter 10. BKtel offers the MIB-files for easy implementation of the SNMP interface into
element/network management systems (EMS/NMS) such as Cablewatch (BKtel), HP Open View
or Rosa (SA former Barco Networks).
The ES10Lb/XLb-versions (ref. to Fig. 2.3.1 b) does not contain an embedded NEC. The RS485
slave interface of the transmitter can be accessed directly, but should be connected to an external
NEC-E (e.g. BKtel’s Ethernet controller NEC-E in BK mechanics).
